How many milligrams is 300 micrograms?

Answer 1

Yes, they both are the same. ****************************** Would it be possible that 300 mcg is 0.3 mg? This is a medication dose I am looking for. The Dr. recommends 0.3mg but I found a bottle with 300mcg is that the same? ****************************** 300 micrograms = 300 x 10^-6 grams = 3 x 10^-4 grams. 1 gram = 10^-3 milligrams. So, 300 micro grams = 3 x 10^-4 x 10^-3 =3x10^-7 milligms
